object of the improvement isv to make a' brick with ribs or projections on one sidev only `of a bed or body plate, whiclrmaybe laid in a wall mortar. l

The objects o'ttheinvention thus set forth in general terms,are attainedv by making'and marketing the brick in the form of' a hollow with interlockingjoints of block having-side and partition walls lon-V gitudinally weakened along the median li'neV for ready separation at the place oi use lnto bricks having bed or'bodyplates with upstandmg ribs forming 1 air channels along each side vand in the medianV portion of each brick; and by providing ll-be'ads o'n-the ribs for partially 'closing the fopenings Por thev side channels andfbrminga bearing for a mortar joint, with the usual longitudinal grooves in the bottom of the brick for interlocking with the mortar ot the joint.

A preferred embodiment of the invention thus generally described, is illustrated in the accompanying 'drawing forming part hereof, in which- Figure l is an end view showing a hollow block cut for breaking into bricks;

Fig. 2, an end section of an eight inch wal made with the improved bricks; Y

Fig. 3, a section of a twelve inch wall embodying the present invention;

Fig. 4, a perspective view of a brick for making an eight inch wall; and

Fig. 5, a perspective view showing the method of building a wall with the ribbed bricks and ordinary corner bricks.

Similar numerals refer to similar parts throughout the drawings.

As shown in Fig. 4, each brick forV an eight inch wall is made of a bed or body plate l extending in width continuously fromV theV inner to the outer faces 2 and 2a formed by the inner and outer upstanding ribs 3 `and 3a of the brick, within which ribs are spaced the upstanding partition ribs 3b, forming an air channel 4 along each vside of the brick,

anda` lo`n,ritu:linalV air channel 5 inthe median portion thereof.r

Theribs forming the-side air channelsV 4 are provided with longitudinal l.beads 6 at or neartheir upper` ends, which eXtend toward each other and close partially but not' entirelythe opening ofthe air channel to such an eXtent as toprevent the dropping of any considerable amount otmortar downward into the channel. At the same time, these beadsrorm a substantially continuons bearing for a mortarv joint; and by locating these beads at an interval below the tops of the ribs, the shoulders' 7 are formed, which give a lateral bearing for `the mortar joint.

rlhe bottom andr inner faces of the bricks are provided with the usual longitudinal grooves=8 and 8a` for engaging the mortar or plaster used in' building' a wall, which `grooves may be dove-tailedin theusnal manner; and the` outer tace 2a of each brick is preferably made s'othat the brick may be laid flatwise in a wall and willpresent a face corresponding to ordina-ry'standardv brick" with 'which r,it may" be' combined"A in the' construction of a wall.

The bricks are also preferably made eight inches or twelve inches, or some other multiple of tour inches in width, so as to form an eight inch wall as shown in Fig. 2 or a twelve inch wall as shown in Fig. 3; in which latter event, an additional pair of partition ribs 3b with L-beads 6 may be provided along the median line of ythe brick, so, as to increase the strength of the wall and provide an additional mortar joint along the middle thereof.

In the construction oi a wall, the bricks are laid with their bed or body plate downward, `and mortar is applied to the tops or" the npstanding ribs and beads, Without how. ever, dropping down to any extent between the L-beads on the ribs; which prevents the side channels from being filled with mortar.

A sufficient amount oi" mortar is used to form a suitable layer on the tops of the ribs 'and to enter the longitudinal grooves 8 in the bottom ot the superposcd brick, so as to form an interlocking mortar joint 9 between the bricks along each side of the wall. A similar joint may be formed along the median linevof a twelve inch wall as shown in Fig. 3.

about eight inches` long'- with a depth of two andthree-eighths inches i The mortarl joints 9 are limited in width to the tops of the ribs forming the side air channels 4, and do not extend across the air channel 5; and itis evident that any water or moisture which may run or seep along the mortar joint from the outer facel of the wall, will be trapped,.in the outer side air.` channel 4 before such water or moisture can reach the air channel 5 in the median portion of the brick; and it is also evident that no water or moisture can pass beyond the air channel 5 so as to affect the inner portions of the wall, and muchlessthe inner face formed by the inner brick.

I claim V l. A brick comprising a continuous bed or body plate having upstanding' side and partition ribsy forming air channels along 3. A brick comprising a continuous bed.

or body plate having upstanding side and partition ribs forming air channels along each side and in the median portion of the brick, there being L-beads on the ribs partially closing the openings of the side channels, and there being longitudinal grooves in the bottom face of the brick opposite the side channels therein.

4L. Hollow wall construction comprising superposed bricks each having a bed or bod),7 plate extending the lfull width of the walls, with upstanding side and partition ribs forming air channels along each side and in themiddle portion of the wall, there being L-beads on the ribs partially closing the opening oi the side channels, with mortar joints between the ribsv and beads of one brick and the bottom of aV superposed brick.

6., Hollow j wall construction comprising 'superposed bricks each having a bed or body plate extending the full width ofthe wall, with upstanding side Vand i partition ribs forming air channels along. each side and in the middle portion ofthe wall, there .beingl L-beads on the ribs partially closing the openings of the side channels, and there Y being longitudinal grooves in the bottoni aceo'f the brick opposite the side air vchannels therein, and a mortar joint laid on the Y tops of the ribs and beads and'entering the grooves to interlock the bricks.
